9.3 A/D CONVERTER (ADC)

9.3.1 Introduction

The on-chip Analog to Digital Converter (ADC) pe-

ripheral is a 8-bit, successive approximation con-

verter. This peripheral has multiplexed analog in-

put channels (refer to device pin out description)

that allow the peripheral to convert the analog volt-

age levels from different sources.

The result of the conversion is stored in a 8-bit

Data Register. The A/D converter is controlled

through a Control Register.
